#### Mathematical Functions

ABS

Absolute Value: ABS(<Double>)
Returns the absolute value of the input.

EXP

Exponential: EXP(<Double>)
Returns the exponential of the expression.

LOG

Log Base 10: LOG(<Double>)
Returns the log base 10 of the expression.

LN

Natural Log: LN(<Double>)
Returns the natural logarithm of the expression.

ROUND

Rounding: ROUND(<Double>)
Returns the input rounded to the nearest integer.

SQRT

Square Root: SQRT(<Double>)
Returns the square root of the input.

#### Trigonometry Functions

By default, each of the trigonometry functions takes and returns radians. If you want values in degrees, use the RAD2DEG function described below.

ACOS

ArcCosine: ACOS(<Double>)
Returns the arc cosine of the expression. For example, ACOS(5.0) returns 0. In general, ACOS(<expression>) returns the arc cosine of the value of the expression.

ASIN

ArcSine: ASIN(<Double>)
Returns the arc sine of the input.

ATAN

ArcTangent: ATAN(<Double>)
Returns the arc tangent of the input.

COS

Cosine: COS(<Double>)
Returns the cosine of the input.

DEG2RAD

Degrees to Radians: DEG2RAD(<Double>)
Returns the input divided by 360 and multiplied by 2p. This converts from degrees to radians.

RAD2DEG

Radians to Degrees: RAD2DEG(<Double>)
Returns the input multiplied by 360 and divided by 2p. This converts from radians to degrees.

SIN

Sine: SIN(<Double> )
Returns the sine of the input.

TAN

Tangent: TAN(<Double>)
Returns the tangent of the input.

Functions where the input is out of range (like ACOS, ASIN, LOG, LN, SQRT and so on, that would cause the computer to crash) return 0.
